Ontario is taking another step to keep families and homes in Ontario safe by making carbon monoxide (CO) alarms mandatory in all residential homes. This new regulation, which came into effect October 15, 2014, updates Ontario's Fire Code following the passage of Bill 77. You must install a CO alarm in your home if you have a fuel-burning appliance, a fireplace or an attached garage. For added protection, install a CO alarm on every storey of your home.

Single-family homeowners and property owners/tenants in buildings that contain no more than 6 suites will have a period of six months to comply (by April 15, 2015).

Residential occupancy owners of buildings with more than 6 suites have 12 months to comply (by October 15, 2015).

CO alarms that have already been installed must be maintained in accordance with the Fire Code effective October 15, 2014.

Failure to comply with the CO alarm requirements could result in a fine up to $50,000 for individuals or $100,000 for corporations.
